These tables list the non-O157 Shiga Toxin-Producing Escherichia coli (non-O157 STEC) test methods that FSIS reviewed and has issued no-objection letters (NOLs). These NOLs were issued in an effort to increase public and industry awareness of available new technologies associated with the implementation of FSIS non-O157 STEC policy in 2012, at a time when reagents and reference strains that were critically necessary to validate STEC test methods were in short supply. The NOLs provide establishments with supporting documentation regarding the reliability of verification testing results.

Since that time, STEC test reagents and reference strains are now readily available and there are STEC detection methods commercially available that have been validated and certified through independent certification entities such as AOAC, AFNOR, MicroVal, or NordVal.

As a result of these positive developments, FSIS has discontinued its STEC test method review and NOL issuance process. However, the Agency encourages the test kit manufacturers to seek certification for STEC method validations through independent certification entities such as AOAC, AFNOR, MicroVal, or NordVal.

FSIS will continue to make available a list of test kits that have been validated for the detection of relevant foodborne pathogens on its website: Foodborne Pathogen Test Kits Validated by Independent Organizations. STEC detection methods that received NOLs and attain certification through independent certification entities will be included in the Foodborne Pathogen Test Kits Validated by Independent Organizations at the next quarterly update.
